IVER NIELSEN, or New ROCHELLE, NEW YORK sarn rv-rasrnnmsron EW LR To all whom/it may concern." 1 v Be it known that I, IVER NIELSEN, ac1t1- zen of the UnitedStates, and a resident of New Rochelle, in the county of \Vestchester, State of'New York, have invented a certain new and useful Improvement in Safety-Fas tenings for Jewelry, of which improvemen the following is a specification.

This invention relates to a safety fastening or click for jewelry, the object being to provide a fastening for bracelets, necklaces, and the like, which cannot become accidentally detached and can only be unfastened by releasing the same at two separate points.

With this object in view my invention comprises a body member or frame connected to one end of the article, and a detachable fastening member, or click, connected to the other portion, together with an additional spring detent for engaging said click and preventing its withdrawal from the body or frame of the fastening except when both springs are released.

In the accompanying drawing, Figure 1 is a perspective view of a jewel setting and fastening for a bracelet or other article of j ewelry, and embodying my improvement; Fig. 2 a plan view of the setting; Fig. 8 a vertical section taken on the line 83 of Fig. 2; Fig. 4 an end view showing the shape of the opening in the frame for receiving the click; Fig. 5 a transverse section taken on the line 55 of Fig. 3; Fig. 6 a perspective view of the click detached from the frame; and Fig. 7 a longitudinal vertical section showing a modified form of safety spring.

As shown in the drawing my improvement comprises a body portion, or frame 8, which may form a setting for a jewel 20, and be connected by means of a link 21, or otherwise, to one portion of a bracelet, or other similar article, while the click member 9,

which is detachably connected to the frame or body portion, is secured by alink 22, to the other end or portion of the bracelet or other article. The frame is formed with a base 10, having guides 11, and an opening 12, into which the click member 9, is adapted to slide,

said click member comprising a slide portion 13, and a spring portion 14:, having a pusher 15, suitably located for engagement with the thumb. After the click is inserted into the opening the spring portion 14:, engages the points 16, of the frame and prevents the withdrawal of the click until the same is released.

. I Specification of Letters Patent. at ed F 9 6 Application filed April 14, 1915. Serial No. 21,201. 1

In order to prevent an accidental or unauthorized detaching of the connection I provide the safety detent formed of a spring 17, mounted at the bottom of thebase of the frame and having a projection 18, eX- -tend1ng 1nto an opening 23 formed in the click 9, the safety spring also having a pusher 19,'extend ing up into a convenient positlon at the side of the frame. The safety spring which may be secured to the frame in anysuitable or preferred manner, is preferably formed of a flat spring blade, and, in case the frame or setting is short, it may be folded over and rigidly attached at its end as shown in Fig. 7, in order to give a sufiicient range of spring movement. When it is desired to detach the connection both pushers 15, and 19, are depressed at the same time thereby releasing the spring 14, from the points 16, of the frame and releasing the detent '18, from the slot or opening 23, so that the click member may be readily drawn out to disconnectthe parts. To fasten the parts together the click member is simply pushed into the opening in the body portion or frame until both springs snap into locked 1. In a safety fastening for jewelry, the

combination of a frame, a click formed of a slide and a spring engaging said frame, a

pusher for depressing said spring, a detent spring mounted-on said frame and having a projection engaging said click, and a pusher for (IBPI'BSSIIIg'thG detent spring in the same direction as the click spring.

2. In a safety fastening for jewelry, the combination of a frame having a baseand guides, a click formed of a slide and spring, and adapted to engage said guides, and a detent spring mounted on said base beneath the click and having a projection for locking the same.

3. In a safety fastening for jewelry, the combination of a setting formed of a frame for'holding a jewel and having a base and guides, a click comprising a spring and slide adapted to engage said guides beneath the jewel, and a detent spring'mounted on said base and having a projection engaging said click.

4. In a safety fastening, the combination of a setting formed of a frame for holding a jewel, a click detachably connected to said frame beneath the jewel, and a detent spring mounted on the frame below the click and having a projection for locking the same.

5. In a safety fastening, the combination of a setting formed of a frame for holding a jewel, a click having a spring for detach- .ably engaging said frame, a pusher at one click.
